If there's one niche celebrity I would never imagine having a sex tape, it would be "This American Life" host Ira Glass. And luckily he doesn't have one! Even so, Julian Joslin decided to imagine what it might sound like. In his parody "sex tape" — which is just audio, no video, of course — the public-radio icon gets not one, but two acts of scandalous sexiness. Ira, whose timid, nasally nerd voice is perfectly impersonated by Joslin, even employs the help of the Planet Money Team to create his Craigslist ad, and every NPR personality appearance heard on the tape besides the fake-Ira is taken from real interviews. If you're a fan of "This American Life" or NPR in general this will make you crack up, but you might not think of Ira the same way ever again.
